I installed root. If I use in terminal, on mac: "source /Users/student/Downloads/root-6.04.14/bin/thisroot.sh" and then "root", the program works fine. But in a tutorial I watch they say that I can write "source /Users/student/Downloads/root-6.04.14/bin/thisroot.sh" in ~/.bashrc. And then I can just type "root" and it should work directly regardless the directory I am in. But it doesn't work. What is the problem?
I'm not sure what is the equivalent directory in mac, but for example, I'm using Ubuntu.
I have:
test.sh
chmod +x test.sh (to make it executable)
then, move it to /bin/ directory
Update ~/.bashrc file, put the code at the bottom part"
export PATH=$PATH:~/bin
Finally, you can run test.sh in any directory you're in.

How can I change my working directory in bash script in windows. I have
~dp0 = C:\test\docker\windows and I want to change my directory to C:\test\build
So it means 2 levels up and then int o build folder
Thanks
Since C:\ is mounted by default into /mnt/c this will work.
Create a .bashrc in your home path by following command:
echo "BUILDDIR=/mnt/c/test/build" >> ~/.bashrc;source ~/.bashrc
cd $BUILDDIR
# Do your work below for example ./configure.
./configure
On my system in Git bash the C:\ root is just /c/ and other dirs from there are whatever they are, so it would be cd /c/test/build/.
You could also still say cd ../../build/.
Good luck.
To change the directory using a bash script is just like you would using normal bash.
cd "C:/test/build"
echo "You're now in the folder, do what you will."
Save the file as .sh and it can be used as such.
Note, when navigation your folders using a bash script remember the directory you'll be starting from is always the home directory.
I try to work with a project in vagrant.
I have made the command vagrant ssh, and connected to VM. Now I need to edit .bashrc file to set path to the source code. But first I couldn't find that file. So I googled and find that the way is call command ~/.bashrc. But doing this I get message, that I have no access to it:
[vagrant#nupic-vagrant:~]$ ~/.bashrc
-bash: /home/vagrant/.bashrc: Permission denied
So what to do now?
UPD.
I can't find the .bashrc file.
When I try to make command ls -a I get following:
[vagrant#nupic-vagrant:~]$ ls -a
. .bash_logout cleanup.sh sshd.sh .veewee_params
.. .bash_profile minimize.sh vagrant.sh .veewee_version
.bash_history .bashrc .ssh .vbox_version .zsh_profile
[vagrant#nupic-vagrant:~]$ locate .bashrc
/etc/skel/.bashrc
/home/vagrant/.bashrc
/var/chef/backup/etc/skel/.bashrc.chef-20130614181911
/var/chef/backup/home/vagrant/.bashrc.chef-20130614181912
[vagrant#nupic-vagrant:~]$
But only the place where I can find some of those files is the directory where cygwin is installed. Pls, see illustrations, they reflect relations between directories vagrant and cygwin.
.bashrc is not meant to be executed but sourced. Try this instead:
. ~/.bashrc
or, equivalently
source ~/.bashrc
See the reference about the . (aka source) builtin.
Note that if what you're looking for is to restart your Bash session after modifying your ~/.bashrc file, you might as well use:
exec bash
That will replace your current Bash session (thanks to exec) by a new session.
If you want to edit that file (or any file in generally), you can't edit it simply writing its name in terminal. You must to use a command to a text editor to do this. For example:
nano ~/.bashrc
or
gedit ~/.bashrc
And in general, for any type of file:
xdg-open ~/.bashrc
Writing only ~/.bashrc in terminal, this will try to execute that file, but .bashrc file is not meant to be an executable file. If you want to execute the code inside of it, you can source it like follow:
source ~/.bashrc
or simple:
. ~/.bashrc
If you can't access the file and your os is any linux distro or mac os x then either of these commands should work:
sudo nano .bashrc
chmod 777 .bashrc
it is worthless
The .bashrc file is in your user home directory (~/.bashrc or ~vagrant/.bashrc both resolve to the same path), inside the VM's filesystem. This file is invisible on the host machine, so you can't use any Windows editors to edit it directly.
You have two simple choices:
Learn how to use a console-based text editor. My favourite is vi (or vim), which takes 15 minutes to learn the basics and is much quicker for simple edits than anything else.
vi .bashrc
Copy .bashrc out to /vagrant (which is a shared directory) and edit it using your Windows editors. Make sure not to save it back with any extensions.
cp .bashrc /vagrant
... edit using your host machine ...
cp /vagrant/.bashrc .
I'd recommend getting to know the command-line based editors. Once you're working inside the VM, it's best to stay there as otherwise you might just get confused.
You (the vagrant user) are the owner of your home .bashrc so you do have permissions to edit it.
Once edited, you can execute it by typing
source .bashrc
I prefer to logout and in again (there may be more than one file executed on login).
Please find the step to fix bash restricted error on Linux servers.
If you are getting below restricted message while try to login to the server by using your credentials , then it might be an issue with lack of directory permissions in the server.
Because of this permission issue we were unable to navigate to required directories and getting error “bash: cd: restricted”
Fix : To release bash restriction error use the highlighted command in Linux server -bash -f
As same if wants to restrict the permission use the highlighted command - bash -r
Once you executed the bash -f command the restrictions will be released from the directories and we can able to proceed with patch scripts.
I created a simple bash script. The script works just fine.
When I run echo $PATH this prints my paths, I have:
/usr/local/sbin:/usr/local/bin/:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
So i moved my script to /usr/local/bin and ran chmod +x mybash.sh. I've even chmod 0777 mybash.sh
Now, when I run ./mybash.sh I just get the "No such file or directory"
Why is this happening and where's the best place to put my scripts
Once the script is in your path, you can run it just with the filename: mybash.sh rather than the path to the file: ./mybash.sh
./mybash.sh means run mybash.sh from the current folder. If you've moved mybash.sh to /usr/local/bin, then it's no longer in ./ (your current folder), so it can't find it.
Either move to /usr/local/bin to run it using ./mybash.sh or just use mybash.sh from any folder once you've moved it into a path folder.
I have a question I have been trying to fix for a while. I want to understand what's the difference between starting a script from the command line and making it executable and then running it from the Finder.
Because this is what I am experiencing;
I have a simple script called trash-files which contains this command:
trash ~/Downloads/*
When I run from the terminal it works as expected; however if I doubleclick the shell script in the finder I see this:
/Users/xx/Desktop/trash-files: line 1: trash: command not found
I hope anyone can tell me why this doesn't work as expected
trash is not a standard command in OS X. Is it something defined in your ~/.profile or a similar file? If so, these are not run for non-login shells, such as those created to run a script.
If you're using homebrew, you could run
brew install trash
which would install the necessary scripts to have the trash command work in the way you're expecting.
There is a folder in your home folder location called
.Trash
The "dot" in front of the folder name makes it hidden while searching for it in finder. You'll have to use Terminal to execute the following command:
cd ~/
ls -la
This will change the directory to the current logged in users home folder, then second command will list files and show hidden files. You can then run:
rm .Trash/*
This will remove everything inside the Trashcan on the dock.
So open TextEdit from the /Applications folder, go to "Format" and make it "Plain Text". Paste in the two lines below.
#!/bin/sh
rm ~/.Trash/*
Save the file as "emptyTrash.sh" (uncheck use txt extension). Save it to your Desktop or wherever you'd like. Then open Terminal, cd (change directory) to where the files is and run this command to make the script executable:
chmod +x emptyTrash.sh
Then you can execute the script by cd (changing directory) to path where the script is, and run:
./emptyTrash.sh
That's it.
I am on Mac's OS 10.6, and I am trying to learn a thing or two about shell scripting. I understand how to save a shell script and make it executable, but I am wondering what I can do or where I can save the file to make it global (that is, accessible no matter what folder I am in).
For example, if I save a .sh file in the /Users/username/ directory and make it executable, I can only execute that script in that specific directory. If I navigate to /Users/username/Downloads, for example, I can't execute the script.
Also, any suggestions of resources for learning more about shell scripting would be helpful. Thanks
/usr/local/bin would be the most appropriate location. Mac OS X has it in the PATH by default
There are two ways to do it -
Put your script in usr/local/bin and make sure it is executable(chmod +x my_script)(This is already set in the path, you can check by doing an echo $PATH)
Create a folder in your home directory called bin. (For your personal scripts)
cd ~ (Takes you to your home directory)
mkdir bin (create a bin folder)
vim .bash_profile (to set path environment variable)
export PATH=~/bin:$PATH (Press i then add this line and then do esc and type :wq)
Now you can just type the name of your script and run it from anywhere you want.
** NOTE: If you want to run the script with a shortened command rather than typing your entire filename, add the following to your .bash_profile:
alias myscript='my_script.sh'
Then you can run the script by simply typing myscript. (you can sub in whatever alias you'd like)
Traditionally, such scripts either go in ~/bin (ie: the bin directory in your home directory) or /usr/local/bin/ The former means the script will only work for you, the latter is for scripts you want anybody on the system to be able to run.
If you put it in ~/bin, you may need to add that to your PATH environment variable. /usr/local/bin should already be on the path.
In mac operating system
Open bash ~/.bashrc file.
add path of your script in your bashrc file , using
export PATH="$PATH:/Users/sher.mohammad/Office/practice/practiceShell"
Open your ~./bash_profile file and add [[ -s ~/.bashrc ]] && source ~/.bashrc
open new terminal window
Now whenever you will open your terminal your script will be loaded
This one is super easy if you are familiar with your bashrc file! This will entirely use just your .bashrc file and takes 2 seconds to accomplish.
(I use Arch Linux Manjaro so I use .bashrc located in my home directory)
The code to be placed in your .bashrc file:
# Simple bashrc method to launch anything in terminal from any directory
YOURCOMMAND () {
cd /path/to/directory/containing/your/script/ && ./YOURSCRIPT
}
As you can see, first you use the simple 'cd' command and give it the directory of the scripts location, then use '&&' so that you can make the next command executed right after, and finally open your script just as you would normally! Super easy and saved right in your .bash file! :)
Hope I've helped someone!
Sincerely,
AnonymousX
On using bash shell, write that script as function and then put it to the .bashrc or source the file which containing that function by "source file_name"
Now execute the script by function call in the shell.
Either saving it in /usr/bin (or any other directory present in PATH) or editing PATH to include the directory you saved it in will basically make it run in any directory.
from the working directory of 'script.sh'" mv [script.sh] /usr/local/bin"( not tested but seems to be the least complex way IMO.)
You should put it in the global executable directory on your machine. I think that would usually be /usr/bin on Unix-based operating systems (this would however most often require super user privileges on that machine).
You could also put it in any other directory that is in the $PATH environment variable, although it would only work for those users who have that directory in that variable.
You can find the value of $PATH by typing echo $PATH in a shell. The directories are separated by :.
